CR-1 is the ultimate tool for subwoofer integration. OVERVIEW The CR-1 Active Subwoofer Crossover has been designed by audiophiles, for audiophiles, offering a powerful combination of subwoofer/satellite tuning features, and a complete commitment to analog signal purity. CR-1 is built around two banks of precision Linkwitz-Riley low-pass and high-pass filters. Multiplying DACs with monolithic ratio matching are employed to adjust the analog circuit’s filter frequencies. This offers superior tracking behavior and far more precise left/right channel balance, compared to conventional approaches. Another of CR-1’s unique and powerful features is a pair of rotary controls that control the damping of each filter bank. These damping controls dramatically improve the acoustic summing th
